It accepts 18 to 4 AWG wire, with terminals that connect from either the sides or the bottom of the block, giving installers flexibility when running wire in tight panel spaces. The block is rated for a maximum voltage of 32 VDC and is built from reinforced polycarbonate, a material chosen for its resistance to corrosion and impact in a marine environment. A snap-on cover insulates the conductive terminals from accidental contact, helping the installation meet ABYC and USCG requirements. The FS81080 meets SAE J1171, the SAE standard for marine electrical devices. It is commonly used as a central distribution point for high-current circuits such as bilge pumps, windlasses, and battery feeds where a Maxi fuse is the appropriate overcurrent protection. Because it is a single-position block, one FS81080 protects one circuit; multiple blocks or a fuse block bank are used for boats with several high-current circuits. The compact housing measures 0.39 x 0.39 x 0.39 inches and weighs 0.26 pounds, making it easy to mount within existing electrical panels or battery compartments.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e FS81080\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Maxi Fuse Block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Marine Fuse Blocks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type Accepted:\u003c\/strong\u003e Maxi fuses, 30-80 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Voltage:\u003c\/strong\u003e 32 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Acceptance:\u003c\/strong\u003e 18-4 AWG, from sides or bottom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Met:\u003c\/strong\u003e SAE J1171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Reinforced polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.26 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size fuses does the Sierra FS81080 fuse block accept?\u003c\/strong\u003e It is built for Maxi-style fuses rated from 30 to 80 amps, the larger blade-style fuses used for high-current marine circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum voltage rating of this fuse block?\u003c\/strong\u003e The FS81080 is rated for a maximum of 32 VDC, suitable for standard 12-volt and 24-volt marine electrical systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat wire sizes can be connected to the FS81080?\u003c\/strong\u003e It accepts wire from 18 AWG up to 4 AWG, and terminals can be wired from either the sides or the bottom of the block.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the fuse block made of?\u003c\/strong\u003e The Sierra FS81080 is made of reinforced polycarbonate, a durable plastic chosen for its impact resistance in marine electrical panels.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the FS81080 meet marine safety standards?\u003c\/strong\u003e Yes, it meets SAE J1171, the SAE standard governing marine electrical and electronic devices, and its snap-on cover supports ABYC and USCG compliance for insulated conductive parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a cover over the terminals?\u003c\/strong\u003e Yes, the FS81080 has a snap-on cover that insulates the conductive terminals from accidental contact.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many circuits does one FS81080 fuse block protect?\u003c\/strong\u003e The FS81080 is a single-position Maxi fuse block, so it protects one circuit; boats needing multiple high-current circuits protected would use additional blocks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions and weight of this fuse block?\u003c\/strong\u003e The Sierra FS81080 measures 0.39 x 0.39 x 0.39 inches and weighs 0.26 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the FS81080 fuse block?\u003c\/strong\u003e It is black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat typical marine circuits use a Maxi fuse block like the FS81080?\u003c\/strong\u003e High-current circuits such as bilge pumps, windlasses, and main battery feed lines typically use Maxi fuses in the 30 to 80 amp range that the FS81080 is designed to hold.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988454158555,"sku":"SIE-FS81080","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/FS81080__13868.1722497397.500.750.jpg?v=1785188201","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-fs81080-marine-maxi-fuse-block-holds-30-80a-maxi-fuses-32-vdc-snap-on-insulating-cover","provider":"Good Vibes Marina","version":"1.0","type":"link"}
